Abstract

The invention discloses a detachable anti-slip screw rod which comprises a first screw rod body, a second screw rod body, a first screw head, a second screw head, a nut, at least one containing groove I, at least one containing groove II, a screwing head and a channel. The first screw head is integrally formed at the upper end of the first screw rod body, a screwing groove I is formed in the upper end of the first screw head, the channel communicated with the screwing groove I is formed in the first screw rod body, the second screw rod body is arranged in the channel, the second screw head is integrally formed at the upper end of the second screw rod body, and the containing groove I and the containing groove II with the upper ends open are formed in the circumferential face of the first screw head and the circumferential face of the second screw head respectively. The screwing head comprises a connector, at least one containing groove III and an inserting groove. Compared with the prior art, the detachable anti-slip screw rod can achieve anti-slip and anti-loosening functions and is detachable.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of a detachable anti-skid screw. 【Background technique】 [0002] The structure of the screw is relatively simple. It generally consists of a rod body with external threads and a head for the wrench to clamp. There are six planes on the outer peripheral wall of the head, and the six planes form a regular hexagon. Because of this structure, People sometimes also refer to the head as a hexagonal head. During use, a wrench is often stuck on the hexagonal head for tightening operation, which is widely used. It will be used in high-speed rail, oil exploration, wind power and other fields. The existing screw does not have anti-slip and anti-loosening functions, and cannot meet the needs of social development. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a detachable anti-skid screw...
